■ GPRS and EGPRS
GPRS (general packet radio service) is a network service that allows mobile phones to
be used for sending and receiving data over an Internet protocol (IP)-based network.
EGPRS (enhanced GPRS), also known as EDGE (enhanced data rates for global
evolution), is similar to GPRS. For more information on the availability of EGPRS
and data transfer speed, contact your service provider.
When you have selected GPRS as a data bearer, the phone uses EGPRS instead of
GPRS if it is available in the network. You cannot select between EGPRS and GPRS
in your phone, but for some applications, you may be able to select either GPRS
or GSM data (CSD—circuit switched data) as the data bearer. The data bearer is
part of the preferred access point and can be changed in Configuration settings
(see ”Configuration settings” on page 58).
The applications that may use GPRS are MMS, instant messaging, browsing
sessions, e-mail, remote SyncML, Java application downloading, and the
PC dial-up (for example, Internet and e-mail).
Before you can use GPRS technology, contact your service provider for availability
of and subscription to the GPRS service and save the GPRS settings for each of
the applications used over GPRS.
GPRS connection
Select Menu > Settings > Connectivity > GPRS > GPRS connection and one of
the following:
Always online—Set the phone to automatically register to a GPRS network when
you switch the phone on.
When needed—Set the phone to establish GPRS registration and connection
when an application using GPRS needs it and to close the connection when you
end the application.
